Christopher Joyce

Christopher Joyce is a correspondent on the science desk at NPR. His stories can be heard on all of NPR's news programs, including NPR's Morning Edition, All Things Considered, and Weekend Edition.

Joyce seeks out stories in some of the world's most inaccessible places. He has reported from remote villages in the Amazon and Central American rainforests, Tibetan outposts in the mountains of western China, and the bottom of an abandoned copper mine in Michigan's Upper Peninsula. Over the course of his career, Joyce has written stories about volcanoes, hurricanes, human evolution, tagging giant blue-fin tuna, climate change, wars in Kosovo and Iraq and the artificial insemination of an African elephant.

For several years, Joyce was an editor and correspondent for NPR's Radio Expeditions, a documentary program on natural history and disappearing cultures produced in collaboration with the National Geographic Society that was heard frequently on Morning Edition.

Joyce came to NPR in 1993 as a part-time editor while finishing a book about tropical rainforests and, as he says, "I just fell in love with radio." For two years, Joyce worked on NPR's national desk and was responsible for NPR's Western coverage. But his interest in science and technology soon launched him into parallel work on NPR's science desk.

In addition, Joyce has written two non-fiction books on scientific topics for the popular market: Witnesses from the Grave: The Stories Bones Tell (with co-author Eric Stover); and Earthly Goods: Medicine-Hunting in the Rainforest.

Before coming to NPR, Joyce worked for ten years as the U.S. correspondent and editor for the British weekly magazine New Scientist.

Joyce's stories on forensic investigations into the massacres in Kosovo and Bosnia were part of NPR's war coverage that won a 1999 Overseas Press Club award. He was part of the Radio Expeditions reporting and editing team that won the 2001 Alfred I. duPont-Columbia University journalism award and the 2001 Sigma Delta Chi award from the Society of Professional Journalists. Joyce won the 2001 American Association for the Advancement of Science excellence in journalism award.

Hurricane Irma is hovering somewhere between being the most- and second-most powerful hurricane recorded in the Atlantic. It follows Harvey, which dumped trillions of gallons of water on South Texas. And now, Hurricane Jose is falling into step behind Irma, and gathering strength.

Is this what climate change scientists predicted?

In a word, yes. Climate scientists such as Michael Mann at Penn State says, "The science is now fairly clear that climate change will make stronger storms stronger." Or wetter.

President Trump pledged to rebuild Houston and Texas bigger and better than ever. However, earlier this month, he rescinded an Obama executive order that required flood-damaged property to be rebuilt higher and stronger. Trump also has proposed eliminating federal flood mapping and the federal government's top disaster agency.

Sea levels are rising and climate scientists blame global warming. They predict that higher seas will cause more coastal flooding through this century and beyond, even in places that have normally been high and dry.

One of nature's most efficient life-support systems is the egg. Eggs evolved over 300 million years ago as vertebrate animals adapted to living on land. And since then, they've taken on numerous shapes, especially among birds.

Biologists have long wondered why there are so many shapes, and what determines each one. Hummingbirds, for example, have eggs like Tic Tacs. Birds called murres produce eggs shaped like big teardrops. Some eggs are more like pingpong balls.

Now, an international team of scientists believes it has solved the mystery of the eggs.

A team of European and Moroccan scientists has found the fossil remains of five individuals who they believe are the most ancient modern humans (Homo sapiens) ever found.

In a remote area of Morocco called Jebel Irhoud, in what was once a cave, the team found a skull, bones and teeth of five individuals who lived about 315,000 years ago. The scientists also found fairly sophisticated stone tools and charcoal, indicating the use of fire by this group.

For 51 years, a small federal program has been paying scientists to keep American waterways healthy. It's called Sea Grant — part of the National Oceanic and Atmospheric Administration — and President Donald Trump"s proposed budget for next year would eliminate it.

There are thousands of parks, refuges and wilderness areas in the U.S. that are kept in something close to their natural state. But one form of pollution isn't respecting those boundaries: man-made noise.

New research based on recordings from 492 protected natural areas reveals that they're awash in noise pollution.

Coal has long had a grip on American politics. That's why politicians worry about its fate. They tout the fossil fuel's contribution to the U.S. economy, but lately they've also been trying to find a way to clean up coal's image.
